Monitoring and Managing the Switch

Traffic Statistics with Receive and Transmit Values

This section describes the types of statistics that display when you

click a port’s bar graph:

• Link Utilization%

There is a separate value for transmit and receive link utilization.

The larger of these two values displays on the bar graph.

The current link utilization for the port is expressed as a

percentage. Each port can transmit or receive data at 100

Megabytes (MB) per second. This statistic shows the percentage

of the maximum link utilization currently being used. Link

utilization is calculated over one-second intervals. The maximum

link utilization is 100%.

• Frames

The number of frames that the port has received or transmitted.

• Four Byte Words Rx

The number of words that the port has received.

• Four Byte Words Tx

The number of words that the port has transmitted.

• Offline Sequences

The number of offline sequence that the port has received or

transmitted.

• Link Resets

The number of link reset protocol frames received/transmitted by

this port from/to the attached switch. The switch transmits a link

reset to initiate the link reset protocol or recover from a link

timeout. The switch receives a link reset from an attached device

if the device wishes to initiate the link reset or recover from a link

timeout.

There are not thresholds for these values. You may determine that

a problem exists by the rate that the value changes.

• LIPS

The number of Loop Initialization Primitives (LIPS)

generated/detected by this port. These cause re-initialization of

the port.
